Abstract

Some stages of the finishing technology of high thickness and surface density textiles such as drying and thermal fixing have a number of problems, especially when using solutions of aqueous polymer dispersions as an application. This manifests itself in the form of migration of particles of the dispersed phase to the surface of the textile web under the influence of heat flow and film formation. This results in deterioration of the operational and special properties of the finished product. A solution to this problem is to use ultra-high frequency electromagnetic radiation for drying. The process of drying and thermal fixing textile woven fabrics with surface density of 460 g/m2 from viscose filaments in the medium of electromagnetic radiation of microwave range was investigated. Structural analysis of the sections of the obtained fabrics proved the effectiveness of the new heat treatment method compared to convective drying.
